Duplicate Ceilings from Linked Model; parameters incorrect

I have successfully duplicated linked ceiling elements from a linked model into my model. I am receiving an unexpected interaction with attempting to pull a parameter from the newly created ceiling in the local file. When I go to pull the “Type” I am returned the “Type Id”. My end goal is to do valve access panel detection based off valves over hard ceilings. I have all components minus the ceiling type to filter down through. Thoughts? Refer to the top portion of the graph (specifically top right. The reported error on the parameter by name node is referencing a non-pointer.

Might be related to the two unloaded links (notice the two nulls coming out of the first node in your graph). Either load the links or filter them out before feeding the link documents through the rest of the workflow.
